PRESS FOR SHAPING META- L SPECIEVICATION forming part of Letters PatentNo. 634,528,"dated Oei-,ober 10, 1899.y

A Y Applicant nel sepemtr e, rees., sarai no. 690,367. montan.; j A

burg, in the county of Allegheny and VState l of Pennsylvania, haveinvented a new and useful Improvementin Presses forShaping Metal,ofwhich thefollowing is a full,clear, and exact description, referencebeing had to ,the accompanying drawings, forming part of thisspecification, in whichv Figure 1 is a side elevation, partly insection, of my improved press. Fig. 2is ahorizontal section on the lineII II of Fig. 1. Fig. 3 is a vertical cross-section of the press. Figs.4, 5, and 6 are detail sections showing the shape ofthe dies and ofthev'beam near the base of thel tapering portion, at the middle of thetapering portion, and near its end, re-

. spectively; and Fig. 7 is anvelevation of the finished pole, partlybroken away.

My invention relates to the bending and shaping ofchanneled Vbeams andother shapes,

such as grooved bars, into articles such as` telegraph-poles, span-wirepoles for electric railways, architectural columns, tbc.; and it z 5consists in an improved machine for carrying Vout this operation.V Y 4In the drawings, 2 represents the base-plate of the machine, having ateach side vertical standards U3, which support the top plate 4.

3o 5 is a longitudinal die-holder secured to the base-plate and havingAlongitudinalribs,.between which is held the bottom die 6 by means ofthe set-screws 7 This die is provided with V a central longitudinalchannel'which is ta-f pered and increaseslindepth and width from one endtoward the other, The portions at the sides ofthis channellare formedinto ribs 8, which rise above the main plane of the top of the die ,andare gradually increased in 4o height and decreased in width from one endof the die toward the other. The sides of the die-body beyond these ribsare gradually Ata-v pered in width and are shaped to receive the liangesof the beam. These sides are pro-` vided with 'recesses placed atsuitable intervals apart and in which' are placed set-screws 9, havingwashers beneath theirheads, these screws acting Aas adjustable gages forthe beam being shaped. The upper die is made 5oy in three parts,the twoouter longitudinal portionsr 1Q b10 being secured tothe bifurcated links11, which form the lower members of toggle -levers having correspondingupper members 12. l These'upper members are pivoted to the upperportionr of the frame, and the several levers are. connected by rods 13,which are adjustable in length,'asshown. These toggle-levers areoperated by a lever 14., pivoted at the end of the machine andlconnected with the end toggle-lever by a link l15, this lever beingoperated by the motive cylinder 16, supported upon the top of the machine and having link connections 17 with the lever.

` The two legs'of each bifurcated lower mem- A ber of the toggles areconnected by square bars 18, wh ich are guided within vertical slots fin longitudinal box-guide 19, placed between these legs and securedrigidly to the frame of the machine.' The central upper die 2O is iittedbetween the side dies and is secured to the lower members 21 of anotherset'of tog- Agles, which areoperated by a motive cylinder 22, theconnections between: the cylinder and 'the toggles being similar to thatabove described for the side dies. This middle die is provided withvertical slots for the passage .of the bars 18, so that it may moveindependently ofthe side dies. e 4

The beam is fed into the machine over feed-v lrollers 23 and between apair of rollers 24, thelower of which may be moved vertically.

kby yoke connections with thelmotive cylinder 25', the face of the upperroller being slightly above the level ot the beamY as it passes into'the machine. Within the ,machine are provided guide-rollers 26, whichcontact with the lianges of the beam and guide and support it in placeon the lower die. The beam is' stopped Vat the proper place upon the dieby 'a stop 27, secured to a swinging U-shaped frame 28, pivoted at Z9and connected with the journals of the lower roll 30, which is locatedat the Yexit end of the` machine and has yoke conwith a roller S2,which, asathe frame is moved l upwardly, contacts with the projectingend of the shaped beam and lifts it after theA upper dies have beenretracted. vIu'order to IOO ' prevent the feed-rollers 24E and 30 frominj uring the hot' beam, I preferablyprovide*limiting-stops for thebearings of these rolls.V

-f In order to prevent the shaped beam from being lifted by the upperdies asfthey rise, I provide a stripper-bar 33, beneath which the yendofthe beam liesthis stripper being a perend with an adjustable stop 86,which is contactedwith by the set-screw 37 upon the lever I4, so as tolimit the movement of this lever, and consequently regulate the amountof descent of the side dies. A similar device is provided for the leverof the middle die.

The operation is as follows: The beam having been passed into themachine with its end Y against the stop, the lever is positioned so thatthe lever llt will contact with it,and motivefluid then being admittedto the cylinder 16 the upper side dies will be moved down a part of'their stroke, as indicated by dotted linesin Fig. 6. Motive iuid thenbeing admitted to the other cylinder 22,the middle upper die is forceddown so as to shape the centralH tapering channel in the beam. The upperside f dies are then `moved down their entire distance, the stop uponthelever 35 having been thrown aside, and the final shape is given tothe web ofthe beam. The, descent of the side dies is then regulated bythe set-screw 37, which strikes the frame of the machine. The upper diesthen being retracted, the roller 30 is lifted, and the roller 32,striking the end of the beam, lifts it free from the lower dies. Thelower roll 24 is then lifted, and the upper roll 24: being rotated thebeam is grasped between them and being fed forward enters the bite ofthe rolls 30 and 3l and is drawn out of the machine. A tapered post orbeam is thus formed, and this tapered portion preferably extends forabout one-half of the entire length of the pole, which I have shown asformed from an I-beam, the article being shown in Fig. '7.

The advantages of my invention will be apparent to those skilled in theart, since a channeled beam or other shape may be quickly and easilyshaped into a form suitable for posts for span-wire columns and similarpurposes.

The particular form of pole which I have shown is of special advantage,as it tapers from about its middle portion to the top and is of greatstrength and stiffness, while it may be easily and cheaply formed fromcommercial beams.

The taper of the beam may be formed by cutting out a wedge-shaped piecefrom the web and pressing the outer portions together, or by folding theweb upon itself, or rolling a beam with a longitudinal corrugated weband then forcing the corrugated portion together, orspreadingthe same bystraightening the corrugation. Further, rthe distance between thestandards 3 may be increased whenr desired by increasing the length ofthe top plate a and either increasing the length of the base 2 orproviding a separate base-plate for each standard, or a greater numberof standards may be provided wheny necessary. Many other changes may bemade in the form and arrangement oi' the machine,

' as well as in the shape of the beam, without departing from myinvention, since I claiml.V A shaping-press having a longitudinal die, aVreciprocating middle die coacting therewith, two separate outer dies atkthe sides of the middle die, said outer dies being rigidly connected toeach other by cross-arms and coactin g with the longitudinal die,andmechanism for reciprocating the outer dies independently of themiddle die; substantiallyas described. f 2.
